Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and goggles.

2. Tire Inspection and Adjustment

Step 1: Check tire pressure using a tire gauge.
- Sub-step: Inflate tires to the manufacturer’s recommended PSI if low.
Step 2: Inspect tires for any signs of damage, such as cuts or bulges.
- Sub-step: Replace any damaged tires with OEM or recommended replacements.

3. Suspension Component Inspection

Step 1: Raise the vehicle using a jack and secure it on jack stands.
Step 2: Remove the wheel to gain access to the suspension components.
Step 3: Inspect the shock absorbers/struts for any visible leaks or damage.
- Sub-step: If leaking, replace the shock absorbers/struts with OEM parts.
Step 4: Check control arms and bushings for wear.
- Sub-step: Replace any worn components.

4. Adjusting or Replacing Suspension Components

Step 1: If necessary, replace shock absorbers/struts.
- Sub-step: Use a torque wrench to tighten bolts to the manufacturer’s specifications (typically around 80-90 Nm, check specific values).
Step 2: Reinstall the wheel and lower the vehicle.

5. Final Checks

Step 1: Perform a wheel alignment to ensure proper handling and tire wear.
Step 2: Test drive the vehicle to ensure the issue is resolved.
